Definitions

• the present invention relates to a battery powered device for a power meter and the associated energy meter.
• the batteries used are typically lithium batteries, like button cells, because of their small size. Given the limited life of this type of battery, a button cell is actually electrically connected to the circuit that it must power when commissioning the meter. In addition, it may be necessary to perform a battery change on the counting device when the latter is in operation.
• a module exists for example in the SL7000 reference electric counting apparatus marketed by the Applicant.
• This module is in the form of a pre-assembly of a button cell, two connection wires soldered to the battery, and a connector connected to the two wires, the connector being intended to cooperate with a connector plug placed in the meter.
• a sealing screw secures the module so as to avoid any fraud in the meter.
• Such a module is a complex piece, so expensive, to achieve.
• connection son and the connector must pass through an insulating tube of the module having a very tapered and complex shape so as to prevent a user can put his finger on the electronic card.
• the electrical connection between the connector and the connector plug must be made using a specific tool, which makes the operation tricky.
• the object of the present invention is to propose a new battery power device for energy counting apparatus, as well as an energy metering apparatus equipped with such a device, in which only the battery is to be changed when it comes to be unloaded, and this, while respecting the conditions of protection for the operator.
• the present invention firstly relates to an energy metering apparatus comprising a printed circuit board, a battery-powered supply device for electrically powering said printed circuit board and a protective cover of said card, characterized in that that the feeding device comprises a support on which said stack can be removably placed, and in that said protective cover comprises an opening through which said support can be inserted and means cooperating with the support in such a manner that to allow the stack to be placed in two distinct positions with respect to the printed circuit board, a first storage position in which the battery is out of electrical contact with said card, and a second so-called use position in which the battery is in electrical contact with said card.
• said support is mounted to move in translation along an axis orthogonal to the plane of the opening, at least one movement of translation of said support being made for the passage of the stack between its storage position and its use position.
• said support has a first housing and a second housing each adapted to receive said stack removably in a plane substantially parallel to the plane of the opening and to the printed circuit board, said means are means for holding the support in the lid in a stable position of use, and the first and the second housing are arranged to allow, in said stable position, to place the battery in the storage position or use depending on whether the battery is located in the first housing or the second housing.
• the known module described above also has the disadvantage of being completely independent of the counting device before assembly, so that it can happen, when installing the counting device by an operator, that the module is not present with the counting device.
• Another object of the present invention is to provide a pre-assembly of the feed device in the counting apparatus before installation so as to avoid any absence of the device during the actual installation of the counting apparatus. This is achieved in a particularly advantageous embodiment of the invention, wherein said support comprises a non-return pin for cooperating with a stop of the cover to prevent removal of the support once it has been inserted through the opening.
• the second object of the invention is the feed device as such, namely a battery feeder for supplying power.
• electrically a printed circuit board of an energy meter characterized in that it comprises a support on which said battery can be removably placed, said support being adapted to be inserted through an opening a cover for protecting the energy counting apparatus so as to allow the stack to be placed in two different positions with respect to the printed circuit board, a first storage position in which the stack is out of contact with said card, and a second so-called use position in which the battery is in electrical contact with said card.
• FIG. 1 illustrates a perspective view and a zoom of the constituent elements of the invention, without the presence of battery, in a possible and preferred embodiment
• FIG. 2 is a perspective view of the support of FIG. 1, again without the battery;
• FIG. 3 is a cross section of the support, still without the battery
• - Figure 4 is a cross section showing the cooperation of the support and the opening of the protective cover;
• - Figures 5a and 5b illustrate in section, two positions of the support through the opening, the support being provided with the battery in its storage position;
• FIG. 6a and 6b illustrate in section, two positions of the support through the opening, the support being provided with the battery in its position of use.
• An energy metering apparatus for example an electricity meter, conventionally comprises a housing, of general external shape substantially parallelepipedic, formed of a base inside which are placed different components, such as a display screen and a printed circuit board 1 (see Figures 5a, 5b, 6a and 6b), a box connection to allow the connection of the meter to the general network, and a protective cover to cover the assembly constituted by the base and the branch box.
• a housing of general external shape substantially parallelepipedic, formed of a base inside which are placed different components, such as a display screen and a printed circuit board 1 (see Figures 5a, 5b, 6a and 6b), a box connection to allow the connection of the meter to the general network, and a protective cover to cover the assembly constituted by the base and the branch box.
• This protective cover forms an outer wall which extends substantially parallel to and away from the plane of the printed circuit board.
• This protective cover or outer wall has an opening 3, substantially circular, to the right of the place where are the electrical connections (conductive tracks or other) of the printed circuit board 1.
• the battery supply device comprises a support 4 on which a stack 5 can be removably placed, this support 4 being insertable through the opening 3. More precisely, in the embodiment described, and as more particularly visible in FIGS. and 3, the support 4 is a piece of insulating material, for example molded, and having two housings 40, 41, each adapted to receive a button-type battery removably. The two housings are superimposed along the axis XX 'corresponding to the insertion direction of the support through the opening.
• the support has a gripping portion 42 for holding and maneuvering the support by a user in the opening.
• the support further comprises two diametrically opposite extensions 43, 44, here in the extension of the gripping portion 42, extending along the two housings, and intended to cooperate with two grooves 20, 21 of complementary shape present on the cover 2 at the opening (see Figure 1), for the insertion and guiding of the support through the opening.
• One of the extensions advantageously comprises a non-return pin 45 intended to cooperate with a stop 22 present in the groove 21 of the cover receiving this extension to prevent the removal of the support a once it has been inserted.
• the lug 45 must have sufficient elasticity to allow insertion of the support into the opening.
• the support 4 is mounted on the counting device by insertion through the opening 3.
• the support 4 of FIG. on the one hand, and the protective cover 2 on the other hand advantageously comprise polarizing means, and a form of holding in position of the stack referenced 46 and 23, intended to avoid any error in the positioning of the support.
• the gripping portion 42 should protrude from the surface of the cover so as to remain accessible to the user.
• the support 4 can no longer preferably be extracted from the opening because of the anti-return spur 45. This makes it possible to avoid, or at least to reduce the risks that the backup power device is missing during the installation of the meter.
• the user may, however, subject the support to a translational movement limited by the anti-return spigot, the lo ng of the X-X 'axis, so as to sufficiently lift the support and access to one or the other. other housing 40, 41 of the support.
• This position of the support is illustrated in FIGS. 5a and 6a.
• the user can thus insert or extract a battery 5 from one or other of the housings 40, 41.
• the support takes up the position illustrated in FIGS. 5b and 5c.
• the battery 5 will advantageously be placed in the housing 40, so as to be in its storage position.
• This position is illustrated in FIG. 5b, where it can be seen that the battery 5 is not in electrical contact with the printed circuit board 1.
• the operator can again maneuver the support 4 to extract the battery 5 from the housing 40 and place it in the housing 41 which corresponds to the position of use of the battery.
• Figure 6b where we see that the battery 5 is in electrical contact with the printed circuit board 1.
• the various embodiments described above allow an easy and safe change of the battery when the latter is worn.
• the feeding device is captive.
• the user can not remove the device, which reduces the risk of fraud.
• Another advantage of the invention lies in the fact that the opening is large enough to allow, before the device is put in place, easy access to the printed circuit board, which may be necessary during the control of operation. of the counting apparatus.
